George Wyndham 3rd Earl of Egremont was born on 18 December 1751 the eldest son and heir of Charles Wyndham, 2nd Earl of Egremont (1710-1763) of Orchard Wyndham and Petworth House, by his wife Hon. Alicia Maria Carpenter, daughter of George Carpenter, 2nd Baron Carpenter of Killaghy, by his wife Elizabeth Petty.

In 1763 at the age of twelve he succeeded to his father’s titles and estates at Petworth in Sussex, Egremont in Cumbria, Leconfield with further land in Wiltshire and also the large estates at Orchard Wyndham in Somerset, the familys oldest possession. He later inherited the lands of the Earl of Thomond in Ireland.

He was educated at Wandworth and Westminster Schools. In 1774 he added O’Brien to his name on inheriting extensive estates in Ireland from his uncle Percy Wyndham-O’Brien, 1st Earl of Thomond. He went on two grand tours to Italy in the 1770s. At the family’s newly built London residence, Egremont House, he associated with fashionable Macaronis.

Egremont was a patron of painters such as Turner and Constable, and of the sculptor John Flaxman who contributed an heroic group of Michael overthrowing Satan for the North Gallery. Turner spent much time at Petworth House and had a studio on an upper floor. He painted landscapes of Petworth, Arundel, and one of the earl’s canal projects, the Chichester Ship Canal. Like his father, the earl also collected French furniture, as when on a visit to Paris in July 1802 during the Peace of Amiens, he bought a pair of five-light candelabra supported by bronze female caryatids, supplied by M. E. Lignereux.

The earl was an enthusiast for canal building, which would allow for agricultural improvement on his Petworth estates by bringing in chalk from Houghton for liming, and coal to replace scarce supplies of firewood, releasing more land for food production. The first venture was the Rother Navigation, making the River Rother navigable to Midhurst. Failing, during the time of Canal Mania, to find any reliable contractor able to undertake the construction most of the work was done by the earl’s own estate workers. Starting from Stopham the Navigation reached Petworth in 1795 and Midhurst in 1796. A branch to Haslingbourne, south of Petworth, was then built, known as the Petworth Canal. This was originally intended to be extended north to link to the River Wey, but following unfavourable surveys the plan was abandoned when the cost of locks needed to reach the north side of Petworth proved prohibitive.

In 1796 the earl purchased 36% of the shares in the Arun Navigation Company, saving it from bankruptcy when it was burdened with the £16,000 cost of building the Coldwaltham cut and Hardham tunnel. Having abandoned plans for a canal from Petworth to Shalford and keen for the nation to have an inland waterway linking London and Portsmouth, safe from natural hazards to coastal shipping and naval attack by the French, the earl turned his attention to linking the River Arun to the River Wey in Surrey. The Arun Canal had extended the navigable length of the River Arun to Newbridge on the road from Wisborough Green to Billingshurst and the Wey and Arun Junction Canal was completed in 1816 to connect to the Godalming Navigation. In 1823 the completion of the Portsmouth and Arundel Canal, including the Chichester Ship Canal, completed the London to Portsmouth route for barges and marked the end of the earl’s investment in canal building.

A number of vessels were named Egremont, including a barge on the Arun Navigation, a brigantine built at Littlehampton for coastal trading and wrecked on the Goodwin Sands after only two years, and later a steam tug used to tow barges across Chichester and Langstone harbours for the Portsmouth and Arundel Canal.

War with France and population growth made famine an ever present danger in the early nineteenth century and there was an urgent need to maximise food production using any land that could be cultivated. In the 1820s, emigration, mostly to Canada, was promoted as a means of relieving rural unemployment and poverty. Thomas Sockett, Rector of Petworth and Egremont’s protégé, promoted the Petworth Emigration Scheme, which sent 1,800 people from Sussex and neighbouring counties to Upper Canada between 1832 and 1837. The earl encouraged those living on his land to join the scheme by offering to pay the £10 per head cost of passage.

The Reverend Arthur Young stayed at Petworth House while conducting his surveys of English agriculture. The earl established a pedigree herd of Sussex cattle from the local breed which was commended by Young who wrote that they “must be unquestionably ranked among the best of the kingdom”. A herd descended from these animals is maintained at Stag Park at the present day. Devon and Hereford cattle were also kept, together with crossbreds. Different breeds of sheep were tried and exotic Tibetan Shaul goats, which produced fine wool for hatters.

Stag Park model farm was created in the northern part of Petworth Park on land cleared of scrub and gorse, consisting of between 700 and 800 acres divided into fields and drained. Land previously used for producing wood fuel could then be released for food production as wood had been replaced by coal delivered by the new canal system. Crop rotations including turnips, tares, wheat, barley, oats and grass were introduced. Potatoes were grown at Petworth and rhubarb as medicine. More unusually Young describes opium production at Petworth, with juices from the incised poppy heads being scraped into earthenware bowls and dried in the sun. The 1797 crop was the largest grown in England and was said to be purer than imported opium.

The 24,000 acre estates in Yorkshire at Wressle and Leconfield in the East Riding, Catton and Seamer in the North Riding, and Spofforth and Tadcaster in the West Riding were also greatly improved with £26,000 spent on drainage and fencing alone between 1797 and 1812.

As well as breeding horses and introducing improved machinery, the earl was keen to continue using draught-oxen when they were going out of favour elsewhere. Young records that by experiment traditional wooden yokes were found to be superior to horse-style collars.

John Ellman, writing in The History, Antiquities and Topography of the County of Sussex by Thomas Walker Horsfield (1835), writes of Egremont:

Horses—This county must not boast of their breed. The Earl of Egremont, with a spirit of liberality which pervades all his actions, gives to farmers, in the neighbourhood of Petworth, the opportunity of breeding from his valuable stud; his lordship also affords the eastern part of the county the same opportunity, by giving the use of one of his best bred horses to Mr. Brown, the venerable training groom at Lewes; his lordship also gives annual premiums to the breeders of the best colts, shewn at Egdean fair, near Petworth.

In 1800 Egremont bought land at Houghton, West Sussex, where he developed chalk pits, which Arthur Young reported as producing in 1808 40,000 tons annually. A canal cut was dug from the River Arun to allow chalk to be moved by barge to lime kilns on higher reaches of the river system, including one at Haslingbourne, south of Petworth.

Paper mills were established at Duncton, south of Petworth and at Iping, west of Midhurst. Near Northchapel a government factory was set up to produce high quality charcoal for making gunpowder from alder wood in coal-heated iron cylinders.

At Spofforth in North Yorkshire the geologist William Smith was employed to search for coal and iron ore deposits. Between 1803-4 £1,000 was invested in sinking test wells, with the use of steam engines to pump out water. Six thin veins of coal were found but were insufficient to be of commercial value.

Egremont maintained a racing stud near Lewes and had his first winner at Lewes in 1777. Assassin won the Derby in 1782, the first of his five Derby winners and five Oaks winners.

Egremont was a member of the Whig party. In 1787 he bought the pocket borough of Midhurst and used it to return his two younger brothers, Charles and Percy, to the House of Commons. Charles only served in one parliament for Midhurst and by 1796 the seat had been sold to Lord Carrington. When the party split in 1792 over the French Revolution he sided with the more conservative faction which supported Prime Minister William Pitt the Youngerin his condemnation of the “wicked and seditious” writings of radicals such as Thomas Paine. He opposed the Poor Law Amendment Act of 1832 which introduced the harsh workhouse system. When the Sussex Poor Law Commissioner William Hawley visited Petworth House in October 1835 he was politely received but was informed that the earl considered the Act “one of the worst measures that could have been devised”.

While Egremont remained aloof from day-to-day affairs, his secretary Thomas Sockett, Rector of Petworth, was deeply involved with poor relief and emigration, and became engaged in bitter disputes with the commissioner over provision of relief to Petworth paupers and the running of the Petworth Emigration Scheme. The national press reported the matter and Sockett, together with other witnesses from Petworth, gave evidence to a House Of Commons Select Committee in March 1837.

A Yeomanry force was revived at Petworth House in 1795 “in case of invasion or internal commotion”, reflecting aristocratic nervousness following the French revolution. Composed of landowners and tenant farmers this cavalry force was naturally commanded by the most powerful landowner, the earl himself. Volunteers provided their own horse while the government paid for maintenance and basic equipment. Egremont himself bought extra arms, helmets, cloaks and feathers from London. Volunteers gained exemptions from taxes on horses, hair powder and from road tolls. By 1798 the force had fifty two members.

Egremont financed the building of a market house at Petworth in 1793 on the market square where bulls had previously been tied to a stake for baiting by dogs. The earl ended this cruel practice and also the practice of “throwing at cocks”, which involved throwing wooden staves at cockerels, the thrower winning a bird if it was stunned or had its legs broken. This had been done at the Midhurst road turning. The Market House or Town Hall was built of stone and adorned at the northern end with a bust of William III.

The earl provided land in 1784 for a new House of Correction, to replace the previous gaol, which had been a squalid place consisting of two unheated rooms and unable to be enlarged to provide the work which was considered essential for the moral improvement of inmates. Delays were caused by petitioning by rate payers against the costs they would have to bear. Thirty two cells in two storeys were built over brick arch arcades to prevent tunnelling out, and the institution opened in 1788 near the present police station and court house. Prisoners were kept in strict solitary confinement, never allowed to speak to each other; even when in chapel they were in individual high sided box pews. Exercise in the outside yards, called “airing”, was also done individually.

Town gas was introduced in 1836 when a gas works was built in Station Road, using coal brought to Coultershaw wharf by barge and later by rail to Petworth railway station. A monument which stands at the north end of East Street was given by the townspeople to show their gratitude to the earl.
The second-hand spire which Egremont bought from a Brighton church for St Mary’s Church became crooked and was taken down in the 20th century, but the great wall which he had built around Petworth Park is still a feature of the area. Built of sandstone masonry over two metres tall, some fourteen miles of wall surrounds the park and subdivides it into three parts, the deer park in the south, then a large area of woodland, with farmland and woods in the northern part. The stone road which runs the length of the park to emerge at the junction of the Ebernoe road with the A283 once continued northward, passing to the east of Northchapel and through Frith Wood to rejoin the A283 London road at a pair of gatehouses which still stand to the north of Northchapel village. This road provided a private bypass of the toll gate at Northchapel for the earl’s family and friends.

Rosalie Duthé

As a young man in London Egremont gave a gilded coach to Mlle Rosalie Duthé, sometimes called “the first officially recorded dumb blonde”, a French courtesan who had moved to London during the French revolution, with whom he was frequently seen at the opera. He was later close to Lady Melbourne whose son William Lamb, later Prime Minister, was widely regarded as Egremont’s son and was said to look remarkably like him. Lamb often spent time at Petworth House as a child and continued to visit Egremont until the end of the earl’s life. Egremont called off a planned marriage to Lady Maria Walpole, a granddaughter of Prime Minister Sir Robert Walpole

Egremont inherited the recently built London townhouse Egremont House in Piccadilly which was known as a haunt of Macaronis. As his country seat he rented Stansted House during 1775 and 1776 while renovation work was in progress at Petworth House. He also spent much time at East Lodge, his house in Brighton, at Kemptown, on the east side of Upper Rock Gardens. He attended Brighton and Lewes races and visited the Prince Regent at the Royal Pavilion. Egremont was known for his philanthropy, and was a founding subscriber of the Royal Sussex Hospital. He also donated £1,000 towards the founding of the Sussex Scientific Institution and Mantellian Museum at Old Steine in Brighton.

Egremont maintained around fifteen mistresses who had more than forty children between them at Petworth House. It is recorded that the peace of the household was often disturbed by disputes between the children, with their respective mothers joining in. The children, certainly of the more favoured mistresses and especially those of Elizabeth Ilive, were educated by Thomas Sockett, a protégé of the earl whom he appointed Rector of Petworth, who also acted as the earl’s secretary. He also had four or five children by Elizabeth Fox and many others by other women.

Charlotte Henrietta Wyndham (1795 – 1870), married John James King and had issue.

Charles Wyndham (1796 – 18 February 1866).

Illegitimate children by Elizabeth (or Eliza) Fox:

Mary Wyndham (29 August 1792 – 3 December 1842), married the 1st Earl of Munster and had issue.

Charles Crole Wyndham (ca. 1795 – d. 30 September 1850).

Laura Crole Wyndham.

William John Crole Wyndham (ca. 1798 – d. 16 November 1865).

On 16 July 1801 Egremont married his mistress Elizabeth Ilive, already having had seven illegitimate children by her. After their eighth child, Elizabeth, died in infancy, Elizabeth Ilive left Petworth to live in London.

Lady Elizabeth Wyndham (1803-1803), died an infant.

The earl died at Petworth House on 11 November 1837. In earlier centuries a horse fair was held at Egdean in early September. It was one of the last occasions on which Egremont was seen in public before his death. The earl gave a £20 prize for the best three year old colt or filly.
As he left no legitimate progeny he was succeeded in the earldom by his nephew George Francis Wyndham, 4th Earl of Egremont, who inherited the Somerset estates, and on whose death without progeny the Earldom of Egremont became extinct. Petworth and various estates in Yorkshire and Ireland passed to Colonel George Wyndham, the eldest natural son of the third Earl, who in 1859 was created Baron Leconfield. Henry Wyndham inherited the family estates in Cumberland.
